webpack2 - 模块解析失败：意外的字符＆＃39; @＆＃39;

Question

我正在尝试使用webpack 2提取css文件，以下是我的webpack代码

var webpack = require('webpack');
var HtmlWebpackPlugin = require('html-webpack-plugin');
var ExtractTextPlugin = require("extract-text-webpack-plugin");


module.exports = {
    entry: './app/main.ts',
    output: {
        path: './dist',
        filename: 'app.bundle.js'
    },
    module: {
        rules: [
            { test: /\.ts$/, use: ['ts-loader'] }
            , { test: /\.css$/, use: ExtractTextPlugin.extract({ fallback: 'style-loader', use: 'css-loader', publicPath: "./dist" }) }
            , { test: /\.(eot|svg|ttf|woff|woff2)(\?\S*)?$/, use: 'file-loader' }
        ]

    },
    resolve: {
        extensions: ['.js', '.ts']
    },
    plugins: [
        new HtmlWebpackPlugin({
            template: './index.html',
            minify: {
                collapseWhitespace: true
            },
        })
        , new ExtractTextPlugin({
            filename: 'style.css',
            disabled: false,
            allChunks: true
        })
    ]
};

当我删除此行

时

  , { test: /\.css$/, use: ExtractTextPlugin.extract({ fallback: 'style-loader', use: 'css-loader', publicPath: "./dist" }) 

和插件中的ExtractTextPlugin对象，我的webpack似乎工作正常，但当我决定提取CSS时，我收到一个错误。 我正在更新package.json文件，只是为了让您了解我正在使用的版本
